A line with a slope of 4 passes through the point (2, 1). What is the equation of this line?

olasank [31]

Answer:

point slope form: y - 1 = 4 (x -2)

slope intercept form: y = 4x -7

Step-by-step explanation:

If you want it in point slope form it would be: y - 1 = 4 (x -2)

but if you want it in slope intercept form, you solve this equation

y -1 = 4 (x-2)

y-1 = 4x -8

+1 +1

y = 4x -7 in slope intercept form

19. Why are the substitution and elimination methods necessary when we already know how to solve systems of linear equations usi

Marizza181 [45]

Answer:

There are situations in which you may be required to solve a system of equations and no graph is present or available. In these instances, substitution and elimination are very effective solution methods.

In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?

Tju [1.3M]

Answer:

$\cos{W} = \frac{9}{41}$

Step-by-step explanation:

Cosine of an angle:

The cosine of an angle, in a right triangle, is the length of the side adjacent to this angle divided by the hypotenuse.

Length of the largest side:

The length of the largest side is 41, that is, the hypotenuse is 41. The hypotenuse is XW.

WY = 9.

This means that the length of the adjacent side to angle W is 9.

What ratio represents the cosine of ∠W?

Adjacent side has length 9, hypotenuse has length 41. So

$\cos{W} = \frac{9}{41}$
